Jordin Sparks, Charli XCX, and Victoria Justice were as sexy as it gets at the Delta Airlines Grammy Pre-Party in Los Angeles on Thursday, and Delta does seem like the weirdest sponsor for a music award show ever, but that's just our opinion, man.

The Shameless starlet shimmered in a gunmetal lace strapless Giorgio Armani dress, along with a silver statement necklace, diamond studs, and a curled updo. Though her best accessory of all her was her big smile!!

And Sophia gave us Old Hollywood vibes with her glamorous orange Vivienne Westwood gown! the draped bodice was just the right amount of sophistication, while the thigh-high slit was all about the sex appeal.
